Abstract Despite a wide array of applications, deep ultra-violet light emitting diodes offer relatively poor efficiencies compared to their optical counterparts. A contributing factor is the lower light extraction efficiency due to both highly absorb

Standard captioning for the deaf and hard of hearing people cannot transmit the emotional information that music provides in support of the narrative in audio-visual media. We explore an alternative method using vibrotactile stimulation as a possible
